Since the error message is: "Cannot convert from type Expression Integer to Float" one might guess to use: (sin (%pi/5))::Expression Float and that would be right although the result is 'Expression Float'. If you really want/need float you can write: (sin (%pi/5))::Expression Float::Float Regards, Bill Page. _______________________________________________ Axiom-math mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/axiom-math
